head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Pure Optimization
A prank-based puzzle game about sequencing traps against a scripted neighbor.

Optimization · Systems & Chaos
A casual zoo management sim about building exhibits and keeping visitors happy.
Neighbours from Hell 2: On Vacation leans Optimization (Pure Optimization); Zoo Park leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Neighbours from Hell 2: On Vacation
light timing on trap execution
Zoo Park
minimal input skill, simple clicking
Neighbours from Hell 2: On Vacation leans a little harder on reads, though the gap is small.
Neighbours from Hell 2: On Vacation
neighbor follows scripted routine, not adaptive
Zoo Park
no adaptive opponent, solo park sim
Zoo Park leans a little harder on variance, though the gap is small.
Neighbours from Hell 2: On Vacation
some randomness in reaction timing
Zoo Park
random visitor/animal events
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Neighbours from Hell 2: On Vacation
puzzle-solving trap sequences per room
Zoo Park
economy and layout management dominate
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
